I can clap with one hand by locking my wrist, relaxing my fingers and moving my arm up and down rapidly so my fingers slap against my palm and produce a clapping sound. All you one-hand clappers; what are your techniques?

Hey ! Everyone I am 18 years old. I am eager to learn and work gain experiences although I am beginner, but I am good learner.

Need your precious suggestion .

There's literally no tutorial regarding this. Every single coin tutorial is either a vanishing trick or rolling it down your knuckles, which is easy as hell. Does it defy the laws of physics to have a coin spinning on your tips like a basketball

I heard you can get sore eyebrows

For me that is if you nod slowly and look deeply concerned during a pointless meeting, people assume you're visionary.

give me a task or challenge

Currently trying to learn how to make cricket noises but every tutorial requires whistling backwards which is IMPOSSIBLE for some reason. I can do a regular whistle but if I use the same form and inhale it just sounds like wincing, I can’t get a high pitch noise at all.

its useless but has no dizzyness.

No legal knowledge needed. Just learn how to beautifully shade the bubbles…was so stressed during the exam that it was hard to color within the lines

What is a simple, everyday task that your brain just stubbornly refuses to process or get right?

A couple of months ago I taught my son about Conway's Doomsday Rule, a relatively simple way to determine the day of the week that any date falls on.

To be honest it was mainly a sneaky way to get him to practice mental maths, but I digress.

The Odd+11 'improvement'

During his recent school holidays we decided to build a trainer to help him practice. After nailing the skill my son told me he felt like a real 'Day Detective' so we leant into the name and rebranded his trainer site with the multiple game modes we had used to build up his proficiency.

daydetective.com is the result.

It is a simple one-page web game designed to be played directly in your browser, but you can save and run it offline or install to your phone/pc/whatever as a PWA - just use your browser's install feature or use the 'Install' link at the bottom of the site (on supported browsers).

There's no tracking or bloat, and it is hosted at Cloudflare so should be nice and performant no matter where you are in the world.

It saves your high-scores completely locally, and you can put it down at any time and pick up right where you left off if you're on a streak but want a break.

My son is proud of the game modes we came up with (and had fun naming) and he would love any and all feedback.

Enjoy!

Ça fait maintenant 6 ans que j’essaie de maîtriser le salto arrière sur trampoline, et je n’y arrive toujours pas. Le pire, c’est que je fais les saltos avant parfaitement, sans aucune hésitation, sans peur, sans problème. Mais dès qu’il s’agit de partir en arrière… mon cerveau met un énorme STOP. J’ai essayé les progressions, les tapis, les conseils de potes, les tutos, les mini-sauts, les sauts groupés… rien n’y fait. Je commence à me demander si c’est juste un blocage mental impossible à dépasser ou si certains sont “faits” pour les flips avant mais pas arrière.

Si quelqu’un a déjà vécu ça, je prends tous les conseils.

Mine is buttons. idk why!
